Hi Terry, Can you add the Dutch language as well: nl: {// Dutch next: 'Volgende pagina', prev: 'Vorige pagina', first: 'Eerste pagina', last: 'Laatste pagina', close_btn: 'Sluiten (Esc toets)', loading: 'laden...', page_info: 'Pagina page_num/page_count ( row_count items )', not_found: 'Niet gevonden', server_error: 'Er is een fout opgetreden tijdens het verbinden met de server', clear: 'Wissen', select_all: 'Selecteer huidige pagina', unselect_all: 'Wis huidige pagina', clear_all: 'Wis selectie', max_selected: 'Je kunt maar max_selected_limit items selecteren', placeholder: 'Kies een optie', items_selected: 'selected_count Items geselecteerd' }, Thanks
